Physical Profile

Compact, thickly built lower-body back who has already added real mass since his junior listing (6-1/185 early in the cycle, measured 5-11/196 at signing) — that is a mid-height, dense frame rather than a tall glider, and the added 11 pounds without losing sprint speed is the important data point. The 10.56 100m (wind-legal) and 6.84 60m are not combine-testing artifacts; they are timed, verified track marks that place him in the top decile of the class for straight-line speed, which is why 247's evaluation credits 'explosive sudden juice.' Gabe Brooks' note that he 'displays quick feet and a relatively shorter stride' is the key translation: a shorter stride at that speed means he can accelerate out of a plant foot without gearing down, which is what makes him a same-play home-run threat instead of a back who needs a clean runway. Frame projects to carry 205-210 without compromising the speed, which is roughly the weight he needs to survive Big Ten interior contact.

Play Style

A big-play, tempo-changing back who wins with vision-to-burst timing rather than power. On film he presses the hole, plants once, and immediately reaches full speed — his production is heavily concentrated in explosive plays (9.3 YPC on limited carries, 29.2 yards per reception), which is the signature of a back whose best trait is separation speed, not accumulation. He is comfortable displaced from the formation and is a real problem on swings, screens, and angle routes out of the backfield, where his acceleration turns a two-yard catch into a chunk gain. The corresponding tendency is that he is a boom-or-bust runner: when the crease is fractionally late or a defender arrives in the backfield, he currently does not create his own yardage, and the negative plays show up. He is not a downhill short-yardage hammer, and he should not be evaluated as one.

Strengths

• Elite verified long speed married to short-area burst — 10.56 100m plus a short-stride, quick-foot profile means he hits top gear inside 15 yards and does not get run down from behind; his senior line (113 carries, 1,051 yards, 9.3 YPC) is a big-play average, not a volume average, and he averaged 26.9 yards per touchdown-producing possession's worth of explosive output rather than churning four-yard gains.
• Genuine two-way receiving threat, not a check-down back — 40 catches for 498 yards as a junior expanded into 18 catches for 525 yards (29.2 per catch) and 5 TDs as a senior, and Washington's spring reports already have him producing on swing passes. That receiving résumé is what gives him third-down and empty-set value as a freshman before he earns first-and-second-down carries.
• Decisive one-cut redirection in the hole — evaluators specifically credit his ability to plant and redirect without losing velocity ('when he puts that foot down, it's bye, bye' — UW RB coach Scottie Graham). Pairs with a career mark of 3,043 rushing yards and 41 touchdowns at Valencia, so the explosiveness has translated into scoring production across three seasons, not one hot senior year.

Areas to Improve

• Contact balance and yards-after-contact against physically superior defenders — the most honest data point available is his own spring: in 32 carries against Washington's defense he was tackled for loss at least six times (roughly one in five). At the high school level his speed let him outrun poor angles; at the Big Ten level, defenders close the crease before he clears it, and he currently loses those collisions rather than falling forward. This is the single gate between his ceiling and his playing time.
• Pass protection and pro-style assignment volume — 113 senior carries is a light workload for a lead-back projection, meaning he has limited reps both in sustained-contact running and in the blitz-pickup responsibilities a Big Ten starter must own. Combined with his age (he turned 17 during his senior year and was the youngest back in the room this spring, per Graham), he needs a year of physical and mental load before he can be trusted on every down.

College Projection

Already on campus at Washington and, because of injuries ahead of him (Jordan Washington's spring-ending neck injury, plus Jayden Limar and Trey Cooley rehabbing surgeries), he took a full 15-practice spring and 32 carries as a true freshman — an unusually large early sample. Realistic 2026 role: change-of-pace and receiving back with a defined explosive-play package, 6-10 touches per game, plus return-game consideration given the track speed. His own coaches have framed the timeline as eventual lead back but not immediate, and the TFL rate this spring supports that. Projected arc: rotational contributor as a true freshman, co-lead by year two once he's carrying 205+, primary back with 15-18 touches a game by his third season. Injury attrition in the UW backfield could accelerate that by a full year.

NFL Outlook

247Sports' evaluation carries a 4th-7th round projection with a high-major eventual-lead-back ceiling, and that is a fair read. The verified sprint speed is a draftable trait on its own — backs who run a legitimate 10.5 100m get looked at regardless of production — and the receiving profile fits the modern committee back who plays 35 snaps and catches 45 balls. What keeps him out of the Day 2 conversation is size-adjusted durability and contact balance: at 5-11/196 with a demonstrated struggle absorbing power at the college level, he has to prove he can take 200 carries a season. Draftable ceiling if he becomes a 1,000-yard Big Ten back with 40 catches; UDFA/priority-free-agent floor with special-teams and gadget value if he stays a 100-touch complementary piece.

Best Fit

A wide-zone or outside-zone-heavy offense that gets him to the perimeter and puts him on the move — one-cut zone schemes are exactly what his short-stride plant-and-go mechanics were built for, and they let him avoid the interior collisions he currently loses. He needs a system that also formats him as a receiver (RB screens, swing game, motion into the slot) rather than one that measures a back by inside-zone volume. Critically, he fits best in a room with an established veteran back ahead of him so he can be deployed situationally while he adds weight — the worst-case fit is a depleted depth chart that forces him into 20-carry, downhill, short-yardage work at 196 pounds before he's ready. Washington's current setup is a reasonable fit on scheme; the injury situation in front of him is the risk, not the design.
